The FES system is designed to capture the fumes emanating from Induction Furnace by placement of canopy hood over it or by side draft hood near by furnace and transport the fume to bag filter via spark arrestor and filter the same to a concentration level of less than 50mg/Nm3 (or as per the norms given by client).
The dust concentration in the fume is in the order of 2 to 3g/Nm3. The coarse particle content is less and that of fines are more and all that is fume. During the process of melting and poking of scrap into the furnace, lot of sparks are generated and these sparks would even travel longer distances and into the bag filter even. To protect the fabric bags from these sparks, a spark arrestor/cyclone is provide prior to the bag filter.

The spark arrestor is then followed by a pulse jet bag filter or set of bag filter

Inside the bag filter, cylindrical bags made of polyester /special material (as per required in the application) are intercepted in the flow path of air and the particles are collected onto these filters by mechanisms interception, inertial impaction and diffusion.

The pulse jet collector is continuous automatic filter capable of filtering dust laden air through a felted non-woven filter media.

The bag filter is followed by a centrifugal fan which generate the driving force in the system and creates negative pressure which cause is suction of fumes.
The clean air from the bag filter is being discharge by id fan/centrifugal fan and vented to same to atmosphere to chimney.
